Fossils in Time
are a paleontologist for the National Park Service. You have
been asked to plan an expedition to uncover new evidence as to why the dinosaurs went extinct. Before you go,
you must write a plan for your expedition that follows the outline
Activity available in PDF format
Write a brief outline
describing your theory of why the dinosaurs went extinct. You
can create your own theory, or describe a theory currently being
tested by other paleontologists.
List some of the existing
evidence that paleontologists have already found that supports your
theory of why the dinosaurs went extinct.
To support your theory,
you will be looking for new evidence in the fossil record.
What are you going to look for, and why will that support your
To which park are you going? What other fossils have been
found there? Why do you think you will find fossil evidence
Outline how you will use geologic maps and other
resources to plan where you are going to dig. What age and type of rock will you be excavating in?
Adaptation for the lower grades:
Students write a short description of one theory of why dinosaurs
went extinct, including a list of existing evidence that
supports the theory, and appropriate maps, timelines or other
graphics to illustrate the theory and evidence.
